The thermal siphon contains a liquid that absorbs heat via thermal conduction from the tank. The liquid is heated to a vaporization point, and the heat from the vaporized liquid is transferred to cooling fins extending from the thermal siphon. ## Claims ### Claim 1 A tank assembly having heat-generating equipment contained therein, comprising: a tank having an opening, wherein the tank includes a first tank and a second tank, wherein the first tank houses a disconnector switch, and wherein the second tank houses a circuit breaker operatively connected to the disconnector switch; and a thermal siphon fixed to the tank adjacent to the opening, wherein the thermal siphon contains a liquid and a gas, and wherein the thermal siphon has a cooling portion. ### Claim 2 (depends on 1) The tank assembly of claim 1, wherein the tank assembly is part of a gas-insulated medium voltage switchgear assembly. ### Claim 3 (depends on 1) The tank assembly of claim 1, wherein the thermal siphon and tank are welded or brazed together. ### Claim 4 (depends on 1) The tank assembly of claim 1, wherein the thermal siphon and tank are bolted together, and sealed with a gasket. ### Claim 5 (depends on 1) The tank assembly of claim 1, wherein the thermal siphon forms a closed loop. ### Claim 6 (depends on 5) The tank assembly of claim 5, further including at least one hose attached to the cooling portion. ### Claim 7 A tank assembly having heat-generating equipment contained therein, comprising: a tank having an opening; wherein the tank houses a disconnector switch and a circuit breaker operatively connected to the disconnector switch; a heat pipe having a side fixed to the tank and sealing the opening, wherein an interior of the heat pipe contains a liquid and a gas, wherein the sealing of the opening of the tank prevents the liquid and the gas from entering the tank, wherein the heat pipe extends beyond a side of the tank, and wherein the heat pipe has a cooling portion. ### Claim 8 (depends on 7) The tank assembly of claim 7, further including a plurality of heat pipes located adjacent to the tank. ### Claim 9 (depends on 7) The tank assembly of claim 7, further including a fin stack fixed to the heat pipe, wherein the fin stack includes fins extending from the heat pipe. ### Claim 10 (depends on 9) The tank assembly of claim 9, wherein the fin stack is configured to dissipate heat to an airflow passing between the fins. ### Claim 11 (depends on 7) The tank assembly of claim 7, wherein the tank includes a first tank and a second tank, wherein the first tank houses a disconnector switch and wherein the second tank houses a circuit breaker operatively connected to the disconnector switch. ### Claim 12 A tank assembly having heat-generating equipment contained therein, comprising: a tank having an opening, wherein the tank houses at least one of a disconnector switch and a circuit breaker; and a thermal siphon having a side fixed to the tank and sealing the opening, wherein an interior of the thermal siphon contains a liquid and a gas, wherein the sealing of the opening of the tank prevents the liquid and the gas from entering the tank, and wherein the thermal siphon has a cooling portion. ### Claim 13 (depends on 12) The tank assembly of claim 12, further comprising a fin stack fixed to a portion of the thermal siphon, wherein the fin stack includes at least one fin extending outwardly from the thermal siphon. ### Claim 14 (depends on 12) The tank assembly of claim 12, wherein the tank includes a first flange and the thermal siphon includes a second flange, and wherein the first flange is bolted to the second flange. ### Claim 15 (depends on 14) The tank assembly of claim 14, further comprising a gasket disposed between the first flange and the second flange. ### Claim 16 (depends on 12) The tank assembly of claim 12, wherein the tank houses a disconnector switch. ### Claim 17 (depends on 12) The tank assembly of claim 12, wherein the tank houses a circuit breaker. ### Claim 18 (depends on 12) The tank assembly of claim 12, wherein the thermal siphon has a main body containing the liquid, and wherein the cooling portion extends away from the main body. ### Claim 19 (depends on 12) The tank assembly of claim 12, wherein the liquid is a dielectric liquid, and wherein the thermal siphon includes walls contains an insulating material. ### Claim 20 (depends on 12) The tank assembly of claim 12, wherein the tank includes a first tank and a second tank, wherein the first tank houses a disconnector switch and wherein the second tank houses a circuit breaker operatively connected to the disconnector switch.
